The larger number represents systolic pressure, or the maximum pressure. The smaller number represents diastolic pressure, the minimum pressure in one's arteries. It is one of the principle vital signs.
That reading would indicate a high blood pressure, 120 over 80 would normal.
High blood pressure reading on a chart indicates that one has a disease. It typically has no symptoms but have life threatening consequences if it doesn't get treated.
149 psi
Arterial pressure
The upper reading is the systolic blood pressure while the lower reading is the diastolic blood pressure. Systole is the contraction of the heart while diastole is the relaxation of the heart.
Blood pressure
normal blood pressure reading
The normal blood pressure is usually between 120-140 mm Hg (systolic) and 80 - 90 mm Hg (diastolic). Anything higher will be considered as high blood pressure
Systolic (the higher number) is a reading of the pressure in your blood vessels when your heart is beating at its maximum strength. Diastolic (the lower number) tells you what the pressure is in your blood vessels when your heart is at rest.
Second
Blood pressure reading: Systolic 124, diastolic 53, pulse 61 -- your opinion?
Because blood pressure changes.
